To all 'whom t may concern Be it known that I, ROY HARRIS, a citizen ofthe United States of America, residing at Winchester, in the county ofLewis and State of Idaho, have invented certain new and usefulImprovements in Devices for Raising Logs, of which the following is aspecification, reference kbeing had therein to the accompanying drawing.

This invention relates to a grapple, and the principal object of theinvention is to provide an improved grapple" which can be usedy forrecovering logs which have become watersoaked and. sunk to the bottom ofa river or lake.

Another'objectof the invention is to prol vide the grapple with animproved means for operating the tongs which engages the sunken logs.

Another object of the invention is to provide the. grapple with animproved means for guiding the line which raises the tongs and alsoprovide means for holding the line in a raised position while loweringthe grapple.

Still another object of the invention is to provide the grapple with animproved socket with which the tongs are pivotally connected, the socketbeing so formed that pivotal movement of the tongs will be limited. i

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspectiveview showing the grapple in use. Fig. 2 is avertical sectional view through the grapple. Fig. 3 is an enlargedfragmentary view of the socket and upper portions of the tongs.- Fig. 4is a perspective view of the socket and broad portions of the tongs.Fig. 5 is a transverse section taken through the socket and upperportion of the tongs as shown in Fig. 3. lFig. 6 is a fragmentarysectional view through the standard of the grapple to show the' mannerin which the sections of the standard are removably connected together.Fig. 7 is a fragmentary perspective view of a section of the standard toshow themanner in which the tong controlling line may be held in araised position. Fig. 8 is a view showing the standard in cross-sectionand the guiding rod for the tong-operating lines in plan. Fig. 9 is avertical sectional view through a log raiser provided with aslightlymodified construction from that shown in Fig. 2. Fig. 10 is a verticalsectional view through the block shown in Fig. 12 with the `tongs inposition. Fig. 11 is a sectional view taken along the line 11-11, Fig.10. Fig. 12 is a pers ective view of the block used in the modi ed formof the invention. Fig. 13 is a fragmentary perspective view showing amodified manner ofv constructing the pins shown in Fig. 7. Fig. 14 is aperspective view of the collar shown in Fig. 13. Fig. 15 is a viewsimilar to Fig. 8 and shows a modified manner ofl constructing the armswhich guide the tong operating lines.

Referring to the drawings, it will be seen that the standard -comprisesa lower section 10 and upper sections 11. There may be as many of theseupper sections 11 as desired, so that the standard will be of suiiicientlength to permit the grapple to reach the bottom of the river. The upperendof each of the sections is'tapered, as shown at 12, in Fig. 6, and isprovided with a transverselyextending opening which is positioned 1nahnement with an opening formed Ain the lower end of the adjoiningsection. A key 13 is passed through the alined openings of the twosections to removably connect the sections together, and is connectedwith the upper section by thechain 14, which chain prevents the key frombecoming lost.

A socket 15, which is internally threaded, as shown at 16, is screwedupon the lower section 10 and is Provided with side ears 17 which areprovided with sockets 18 as shown in Fig. 3. The tongs 19 have theiryupper ends 20- reduced and Hattened and pivot-ally mounted in thesockets 18 upon the pivot-pins 21. These sockets 18 are constructed asshown in Fig. 3, so that the ton s will be prevented from movingdownward y beyond' a desiredamount and also revented from movingupwardly beyond t e horizontal position indicated by the dotted linee inFig. 1. A ring 22 is connected with a lip 23 and is provided so that aline or cable 24: can be connected with the standard are connected.These lines 28 pass throughthe eyes 29 of the cross-rod 30 and havetheirplower ends connected with the eyes 31 of the tongs 19. By drawingthe line 25 upwardly the tongs can be raised from the position shown inFig. 1 to that ind1cated by the dotted lines, thus permitting the tongsto be held in an open position 1n order to permit them to more readilyengage a short log. A short rod is carried by the l1ne 25 between t-heeyes 23 and the ring 27 and forms an abutment. which is intended to restupon the pins 33 whenever it is desired to support the tongs in a raisedposition. This device permits the grapple to beeasily operated since thetongs can be opened and then supported in the open position while thegrapple is being lowered. It should be noted that the eyes 26 extendoutwardly beyond the ends of the pins 33 so that when the grapplereaches the bottom of the river the line can be drawn upwardly and thiswill cause the abutment to be-drawn from the ends of the pins. As soonas the line is released again, the abutment will pass the ends of thepins 33 and permit the tongs to lower.

The operation of this device is as follows: When it is desired torecover a log from the bottom of a river the tongs are raised i and thegrapple is then lowered above the 4llogs. The sections 11 are connectedwith the lower section until a sufficient number are in place to permitthe grapple to reach the bottom of the river and the line 25 is drawnupwardly to release the tongs and 1 permit them to Swing downwardly.upon each side of the log. When the tongs have engaged the log, asshownin Fig. 1, the grapple 24 is drawn upwardly, thus raising thegrapple and drawing the log to the surface of the river. As the grappleis raised the sections 11 are removed, thus permitting the grapple to beused conveniently. It should be noted that by having the tongs preventedfrom moving inwardly beyond a desired amount, there is no danger of thepoints on the tongs .cutting into the logs a suflicient distance to cutentirely through the log and thus weaken the log to such an extent thatthe weight of the log will cause the points of the tongs to cut theirway through, thus permitting the log to again sink to the bottom of theriver.

The form shown in Fig. 9 is similar to thatshown in Figs. 1 and 2, withthe exception of the construction of the block 15,

guiding rod 30 anti supporting pins 33. The block 15, shown in Fig. 12,is provided with slots 18 in its end port-ions 17 to take theJ place ofthe pivot ears 17 shown in Fig. 4 and is provided with an extension 34in which is formed the threaded opening 35. The eye 36 is .locateddirectly above the tongs 19 as shown in Fig. 9 and it will thus be seenthat the tongs will be in alinement with the eye 36 instead of being inalinement with the standard 10, as shown in Fig. 2.

A metallic strip 37 has its end portions formed into the eyes 38 and hasits central portion bent to form the yoke 39 which extends partiallyaround the standard 10. A securing clamp 40 is secured to the strip 37and extends about the remaining portion of the standard 10, as shown inFig.- 15, so that the strip 37 will be securely held in place. Thisstrip 37 takes the place of the rod 30 and does away with the need of`forming an opening in the standard. The coil 41 shown in Fig. 14 isplaced about the standard beneath the eye-pin 26 and is held in place bya securing pin 42 extending through the inner ends of the tongs 43.These tongs 43 extend at an angle, as shown, and take the place of thepins 33. By use of this collar it is not necessary to form openings inthe standard for the pins 33 and, therefore, the standard will not beweakened by having openings formed in it.

The construction and operation of the form shown in Fig. 9 is similar tothat shown in Fig. 1 and, therefore, it is not necessary to describe themethod of operating the form shown in Fig. 9.
